Mcro::Range::TExtendedIterator< Iterator, Policy > Struct Template Reference

Unreal's own iterators are not STL compliant (they are only compatible with range-for loops) so they cannot be used with more advanced STL algorithms or other third-party libraries which may expect the full iterator interface compatibility. For that TExtendedIterator fills in the missing components and wraps Unreal iterators to be fully STL iterator compliant. More...

Detailed Description

template<CBasicForwardIterator Iterator, FExtendedIteratorPolicy Policy = {}>
struct Mcro::Range::TExtendedIterator< Iterator, Policy >

Unreal's own iterators are not STL compliant (they are only compatible with range-for loops) so they cannot be used with more advanced STL algorithms or other third-party libraries which may expect the full iterator interface compatibility. For that TExtendedIterator fills in the missing components and wraps Unreal iterators to be fully STL iterator compliant.

TExtendedIterator makes a copy of the Unreal iterator it wraps for internal storage, which should not have significant side effects, but emphasis is on SHOULD.
